Answer:
[tex]\boxed{ \text{A double displacement reaction} }[/tex]
Explanation:
In a double displacement reaction, the metal cations change partners with the anions.
3Na₂CO₃(aq) + 2AlCl₃(aq) ⟶ 6NaCl(aq) + Al₂(CO₃)₃(s)
This is also a precipitation reaction, because the aluminium carbonate is insoluble and precipitates from solution.
